A new biosensor platform for the detection of bacterial pathogens, specifically demonstrated with E coli, has been developed based on long-range surface plasmon-enhanced fluorescence spectroscopy (LRSP-FS).

This study investigated the ability of human osteoclasts to grow on titanium and aluminum, and directly corrode the metals leading to the release of corresponding metal ions, which are believed to cause inflammatory reactions and activate osteoclastic differentiation.

Chronic arsenic poisoning is perhaps one of the most insidious environmental disaster affecting tens of millions of people on the Indian subcontinent and elsewhere. An ongoing study of the problem of arsenic-contaminated drinking water uses atomic absorption spectroscopy to underpin its analytical data.

A novel LA-ICP-MS methodology was developed for analyzing ultra-trace element impurities in rough diamond for origin determination ("profiling") using binomial logistic regression which produced a better overall correct classification than linear discriminant analysis.

Samples of tinned sardines, originating from six countries have been analyzed for total arsenic, cadmium, lead and mercury content using AAS. The analysis provides a useful baseline for a foodstuff - small pelagic fish - that could become increasingly important in a possible sustainable future.

A compositional study was carried out of the impact melt and impact melt breccia clast populations of meteorites representing regions of the lunar surface that were not visited by the US Apollo or Soviet Luna sample return missions, using in situ electron microprobe and LA-ICP-MS techniques.

Ab initio molecular dynamics simulations and detailed analysis hint at how conditions on the early earth might have been ripe for a cometary impact to generate small organic molecules. The study suggests that the formation of molecules akin to the simple amino acid glycine may have been viable. Follow-up spectroscopic studies may demonstrate the validity of the hypothesis.

The potential of high-precision calcium and lead isotope ratio measurements using LA-MC-ICP-MS to aid distinction between four genuine and five counterfeit pharmaceutical packaging samples and further classification of counterfeit packaging samples has been evaluated.
